"As a married person myself, I don't know what it's like to be told I can't marry somebody I love, and want to marry," she said. "I can't imagine how that must feel. I definitely think we should all have the right to love, and love publicly, the people that we want to love."

Underwood speaks frequently about her faith, and her hit song “Jesus Take the Wheel” helped secure her large Christian following. Yet Underwood says her support for loving and committed same-sex couples comes because of her Christian values, not despite them:

"Our church is gay friendly," she said. "Above all, God wanted us to love others. It's not about setting rules, or [saying] 'everyone has to be like me'. No. We're all different. That's what makes us special. We have to love each other and get on with each other. It's not up to me to judge anybody."
